GRATES AND ASH-SIPTERS IN COOKING-STOVES.

'IO ALL WHOM IT MAY CONCERN-2 Be it known that I, DANIEL E. PARIS, of the city of Troy, in the county of Rensselaer, and. State of-New.

York, have invented new and useful Improvements in Ash-Sifters and Fire-Grates; and I do hereby declare that the following is a clear and, accurate description of the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, like letters representing like parts, in which- Figure 1 is a perspective view of a stove with a part of the outer casing removed, showing the fire-grate and ash-sitter as applied to cooking-stoves. I

Figure 2 is a perspective view of the grate and ash sifter shown more in detail.

Figure 3 is a sectional side view of the grate and sifter, showing their relative position to each other.

Figure 4 shows the ear of the sifter, together with the movement of the bail, which is attached to'the surrounding pan F. I I

Figures 5 and 6 show, respectively, the handles to the grate and sifter.

Figure-7 is a top view of the grate, showing the extent of its movement longitudinally.

Figure 8 shows the'ash-pan, which is situated below the sifting-grate in the hearth of the stove L.

It has long been desired to construct a fire-grate that could be operated from the outside of the stove. I Secured this in my patent-of December 31, 1867-; but I have made some improvements in that grate, which are herein shown and described.

It has been equally desirable to secure some cleanly and expeditious method of separating the ashes from the coal after they fall from the fire-grate. 'Ash-s'ifters in the hearths oi' stoves have been used for a great many years, but they were never made movable, and made to operate inside the stove, until the invention of Mr. John M/Tuller, whose application for a patent was filed on or about the 5th of August, 1850. In that invention the sifter was made movable in the bottom of an ash-pan, as in this invention, and the ashes were separated inside of the hearth of the stove, while all the covers and dampers were closed, and his sifting-grate was moved by a handle-or lever from the outside of the stove. Thus, I claim here nothing new in principle. I claim, however, that my arrangement is an improvement over Tullers invention; that my sifting arrangement is more simple and convenient, and farless liable to get out of order, while the stove can be fitted much more closely, so as to better control the draught by regulating the admission of cold air.

The construction of my fire-grate was described in my previous patent, especially as regards placing the journals a b, fig. 2, eccentrically at either side of the grate. In this invention, the'front grate I3 is the same as in the former, as regards the attachment of the journal a, while it differs from that in being independent of the back grate A. In the former invention the front grate lay on the back one, while in this its back edge lies on two rests, pp, as seen in fig, 7. In the former invention the back grate had the journal Z) attached at or near its front/side, whileihere it is attached to its rear side, its front side lying on the rests 19 p, the same as the front grate, the one being the converse of the other; and while their movement is the same as in the former invention,the extent of which is shown at Q Q, in fig. 7, yet their dumping arrangement is altogether difi'erent. Dne or both of these grates can be dumped.entircly independent of the other, and is done by'simply-pushing the grate inward sufficiently far to let the slots 1' 9 come over the rests 1), when the grate falls, of its own weight, perpendicularly downwards, as shown in the dotted lines below the grate in fig. 3, thus dumping the entire con tents into the sitter F, being conducted thence by the plate I.

Each grate is placed back in position again by being hroughtup horizontally, and then pulled a little outward till the edge is caught on the rests p p, and they are kept in position and prevented from dumpingwhile the grate is being shaken, because of the points on the shaker E, at 0 e, which latter strike against the side or jamb of the stove before the grate goes suiiiciently far backward to'aliow it to dump.

The points 0 9 may be of any length-required, or there may he stops on the side of the stovc,'as seen at X in fig. 1, by which means the points 0 0 may be shortened or omitted altogether.

It matters nothow violentl or how fast the rate ma be shaken it cannot ossibl dum. because it can-' y a Y 1 V P l' i" not go back sufficiently far to do so while the shaker E is attached to the journals a b.

In order to dump the grate, I change ends with the shaker, and put the eye y on the hooks of thc journals a b, and push them inward till they dump; and thi dumping arrangement could not he better, as the grate is q v 2 Tsoss entirely freed of its contents at once, because, dumping thus from the middle of the fire-box, a plenty of room ishad to discharge the whole contents of the fire-chamber at once without clogging. I

The cross-bars c c are only placed over the grate when it is used for wood, and the n they beome exceedingly valuable, forthey hold up the wood and brands of fire while the coals are dumped into the sifter below for broiling purposes.

These bars cannot be used with anyother' kind of grate, because in all other kinds :1. part of the grate when dumped turns upward as well as downward, and these valuable support-bars. cannot be used with any kind of grate that turns upward when dumped.

4 The -value of the sifting arrangement will-be seen from the foregoing, for if the stove is usedto burn wood, the live coals can be dumped downon to it, and the .ashes at once sifted into the pan below by means of the shaker J, seen in fig. 2. Thus the b'roiling-iron is laid over the clear coals, the plate M. being removed, and the smoke passes upward through the fire-box.

The chief improvement in this sifter over Tullers invention is that it is divided into two parts, is provided with a-bail that moves the sifting-grate in and out at pleasure, and: is always read'y for use, the journals I I. being always out, and ready to receive the shaker-J whenever the bail is down or the cover M in its place.

d When they are out and ready for work, thefholes through the front of the hearth-sink L are closed up, so

- as not to injure the drought of the stove by the admission of too much cold air, and so as tofpreventlthe escape of ashes into the room. p

Whenever the bail is downhthe sifting-grates are left free to work, as seen in fig. 4, but whenever thebuil is raised up, the sifting-grates are caught by the ears K, and pushed backward so that the 'sifter will lift freely out of the hearth L, so that its contents may be emptied the same as though its bottom were not movable.

Thus it willbe seen that, whether coal or wood is used, the coals-can be sifted from the ashes wholly inside of the stove; that the separation is perfect and complete, and without any dust or ashes in the room.

It will be seen also that these sifting-grates are operated on the same principle as the fire-grataexc'ept they are not made to dump, that process not being required.

The sifting-pan F is made-without any bottom other than the sifting-grates G and H, which are held to the ppm 15 by rests at either side, andby the inverted Ts, c and d, at the centre, as seen in fig. 2.

The device of moving the sifting-grate and out,'by 'rneans of abail, to the pan.F, is considered simple and valu able,.for when the bail stands up perpendicularly, and is ready for use, the grates are, by the movement of the bail, shoved backward, so that the pan can be lifted directlyout of the hearth L, while, by the I simplemovement of putting the bail down again, so as to put on the'coverM, the journals I-I immediately move outward, so as to be ready to receive the shaker J, which latter cannot possibly be takenofi the journals I I except the gratesbe left in proper position to be caught by the bail R. The next time,-it is moved upward by meansof the ears K and the ping, seen in fig.

It will beseemthe bail R is attached to the pan F, and operates entire-grates G and It may equally wellbe attached to the grates G- and H, and made to operate on pins, lugs, or slots cast inor on the pan F: The principle would be the some in either case. I I I I I The top-of the ash-pan T, seen in fig. 8, surrounds thebottom of the pan F, so as to catch all the ashes, while the two half rounds VV are made at the top of its front side, .to accommodate thejournals II, and a part of the top of the back side is cut away, so as to accommodate the sifting-grates as they vibrate backwards and forwards.

The positions of the fire-grates B and A may, if desired, be interchanged, the back grate brought to the I front, so as to bring the two journalsa and 6 together. l i l Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

' 1. A fire-grate, made in two' parts, having-journals eccentrically attached, underranged to dump or discharge its contents 'from the centre of the fire-box, whenever the two parts are moved off their'supports and allowed to fall down perpendicularly, substantially as described.

2. The elongated points on, on the shaker E, or stepson the side-plate of the stove for the shaker to strike against, or an equivalent therefor, which shall prevent-the shaker from driving either part of the grate in too fanwhen in use, and so as to preVentit-X'rom dumping while in operation.

3. The support-bars we, placed over and in combination with avibrating fire-grate, for the purpose herein described and set forth. I

4. A sifting-pan, situated below or in front ofa fire-grate, having attached to its bottom, sides, or ends, two or more open movable sifting-grates or sieves, and arranged to vibrateinside of the stove, by means of a pronged handle or doubleshaker, operated from the outside of the stove, substantiallyas, herein described and set forth.

5. The lifting and sifting-grate G H, or equivalent, in the hearth of a cooking-stove, provided with journals I I, projecting through the hearth, and adapted to be shaken or, vibrated from the outside, substantially as shown and-describcd. I

6. A bail, attached to a sifting-pan, or to its movable bottom grate or grates, and so arrangcdas to move the grate or grates backwards and forwards,- by raising said bail up perpendicularly and letting it down horizontally, substantially as herein shown and-described.
